Aliens in London?

The aliens are taking over London:
Strandbeesten — Trafalgar Square - 9
(Actually, this is a picture of one of Theo Jansen’s Strandbeesten, encamped in London for the summer, courtesy of the ICA.)

And this must be the mothership:
Serpentine Pavilion - 7
(And this is the summer’s Serpentine Pavilion, designed by architect Rem Koolhaas and Cecil Balmond of Ove Arup.)
